| Abstract | Community acceptance of geothermal projects is crucial for their successful implementation. This study conducts a global review to examine the factors influencing community acceptance in Germany, Switzerland, Japan, and Indonesia. Switzerland is included due to its geographical and cultural proximity to Germany, as well as its similar geothermal potential despite differences in its geologic setting. Japan, as part of the Pacific Ring of Fire, endows it with a notably high geothermal potential. However, cultural traditions might negatively affect community acceptance of geothermal projects. Additionally, Indonesia, with its diverse socio-economic landscape and rich geothermal resources, offers a unique perspective on acceptance factors. Preliminary results indicate that project organization and processes, and environmental considerations are central acceptance categories across these countries. Our observations suggest, furthermore, that political acceptance factors may play a more prominent role in Japan, while technological factors appear to be more significant in Germany and Switzerland. In Indonesia, local socio-cultural values and environmental impacts are emerging as important components influencing acceptance. By comparing these trends, we aim to identify the varying influences of community acceptance factors across different cultural, geologic, and geographical conditions. Our findings aim to provide a science-based foundation for actionable recommendations in the implementation of geothermal projects. By understanding the various acceptance factors across different countries, we provide a foundation for detailed research on community acceptance. As a result, our research offers views on different perspectives in these four countries. This can be a starting point for country-specific profiles to understand nation-specific acceptance preferences. |
